Description

Technical Field

[0001] This invention relates to the field of load-bearing frame technology, specifically to a prefabricated adjustable load-bearing frame with overhead support points. Background Technology

[0002] In the construction and renovation of data center server rooms, the load-bearing support frame of the server racks is a key structure for ensuring the safe operation of equipment. Currently, traditional server rack support frames are mainly field-welded structures, with a small number being simple angle steel assembly structures. In terms of construction methods, existing technology requires on-site measurement and cutting based on the server rack layout and the location of the building's load-bearing beams. Steel materials such as channel steel and I-beams are then welded together to form a frame, which is then directly fixed to the building floor slab or load-bearing beams using expansion bolts. This method involves on-site welding work, posing a fire hazard to existing low-voltage electrical equipment in the server room. Furthermore, once welded, the structure is fixed and cannot be adjusted according to actual on-site conditions. Regarding ground adaptability, server room floors are generally uneven, and existing welded support frames are rigid and lack height adjustment capabilities. Leveling with shims is required on-site during installation, which is not only cumbersome but also prone to uneven stress on support points, leading to problems such as support frame deformation and floor slab cracking. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable prefabricated overhead support frame to solve the problem that existing welded force-releasing frames cannot adapt to uneven ground conditions.

[0004] To achieve the above objectives, the present invention provides a prefabricated adjustable overhead support frame with the following technical solution:

[0005] A prefabricated adjustable overhead support frame includes: Two rectangular frames are arranged parallel to each other, each rectangular frame includes multiple support beams, and the support beams are provided with assembly grooves along their length direction, and multiple bolt connectors are slidably fitted in the assembly grooves; An adjustable support leg is disposed between the upper and lower rectangular frames. The end of the adjustable support leg is connected to a connector. The connector has multiple mounting holes in its circumference. A bolt connector passes through the mounting holes to fasten the connector to the support beam.

[0006] As an optimization of a prefabricated overhead adjustable support frame, the adjustable support leg includes a threaded sleeve and a screw, with the screw threadedly connected to the threaded sleeve.

[0007] As an optimization of a prefabricated adjustable load-bearing frame with an overhead support point, the side wall of the threaded sleeve is provided with a locking screw, which penetrates the side wall of the threaded sleeve and abuts against the screw rod.

[0008] As an optimization of the prefabricated overhead adjustable load-bearing frame, it also includes diagonal bracing, which is set between the upper and lower rectangular frames. The ends of the diagonal bracing are rotatably connected to connecting plates, and the connecting plates are fastened to the support beams through bolted connections.

[0009] As an optimization of a prefabricated adjustable load-bearing frame with an overhead support point, a shock-absorbing module is fixed to the support beam by the bolt connection. The shock-absorbing module includes a mounting bracket, a spring, and a rubber damper.

[0010] As an optimization of the prefabricated adjustable support frame, both the rectangular frame and the adjustable legs are hot-dip galvanized for corrosion protection, with a galvanized layer thickness of not less than 85μm.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The adjustable outrigger adopts a threaded lifting structure. Each outrigger can be adjusted independently with an adjustment range of ±20mm. It can accurately compensate for the height difference caused by the ground tilt, so that the upper frame always remains horizontal. There is no need to add shims on site to level it. It effectively avoids problems such as uneven force on the support points, deformation of the scaffold and cracking of the floor slab caused by uneven ground. (2) The assembly adopts a bolt connection method, which eliminates the need for welding, cutting and other hot work operations, thus eliminating the fire safety hazards of weak electrical equipment in the computer room. It also has low requirements for worker skills. One person can complete the installation of a single set of dispersive frame. The construction efficiency is improved compared with the traditional welding solution. It can be quickly disassembled, reassembled and relocated, adapting to the needs of computer room layout adjustment, expansion or computer room relocation, and realizing long-term and multiple reuse, avoiding the waste of resources from repeated steel purchase and processing.

[0012] (3) Metal components are hot-dip galvanized for corrosion protection in the factory, with a zinc coating thickness of not less than 85μm. The service life is extended by 5 to 8 years compared with the traditional solution, which greatly reduces the later maintenance cost. Attached Figure Description

[0016] To make the technical solution and advantages of the present invention clearer, the present invention and its beneficial effects will be described in further detail below with reference to specific embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0018] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0019] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail below.

[0020] This application provides a prefabricated, adjustable overhead support frame, primarily used for load-bearing and stress-dissipating installation of server racks in data center computer rooms. All components are prefabricated in the factory, and assembly on-site is achieved using a fully bolted connection method, eliminating the need for hot work. The frame's height can be adjusted to accommodate uneven ground conditions. The technical solution is as follows: Reference Figure 1The prefabricated adjustable load-bearing frame with overhead support includes two rectangular frames 1 arranged parallel to each other, serving as the upper and lower frames, respectively. Each rectangular frame 1 is composed of multiple support beams 11 vertically spliced ​​together. The support beams 11 are prefabricated using hollow steel or channel steel, possessing good bending strength and load-bearing capacity. Assembly grooves 12 are formed along the length of each support beam 11. The cross-section of the assembly grooves 12 is an inverted "T" shape, with the opening facing the opposite side of the two rectangular frames 1. Multiple bolted connectors 13 are slidably fitted within the assembly grooves 12. Each bolted connector 13 includes a bolt and a mating nut. The bolt nut is inverted and embedded in the wide portion of the assembly groove 12 and can slide freely along the groove. The bolt rod 22 extends from the narrow gap of the assembly groove 12 to engage with the nut for a secure connection.

[0021] Reference Figure 1 and Figure 2 Adjustable support legs 2 are installed between the upper and lower rectangular frames 1 to support the upper frame and adjust its horizontal height. Multiple adjustable support legs 2 are configured according to stress distribution, and each adjustable support leg 2 can be raised and lowered independently. Connecting members 3 are welded and fixed to the upper and lower ends of the adjustable support legs 2. The connecting members 3 have a plate-like structure with multiple elongated mounting holes 31 around their circumference. After installation, part of the connecting member 3 extends beyond the outer edge of the rectangular frame 1, forming a cantilevered support point. This cantilever support point is used to connect with the support columns or joists under the raised floor of the computer room, allowing the raised floor structure to participate in load-bearing and forming a multi-support load transfer system. The connecting member 3 is fastened to the support beam 11 via bolt connectors 13. Specifically, the bolt shank of the bolt connector 13 passes through the mounting holes 31 on the connecting member 3 and is tightened with a nut, thereby fixing the end of the adjustable support leg 2 to the support beam 11. Since the bolt connector 13 can slide within the assembly groove 12, the connection position between the connector 3 and the support beam 11 can be flexibly adjusted according to actual installation requirements. In this embodiment, three adjustable legs 2 are installed on the same support beam 11, located at the front, middle and rear ends respectively. The three legs form a three-point support structure, which can provide a stable support foundation for the upper frame.

[0022] When the floor slab is uneven, the lower frame will tilt as it rests on the uneven surface. In this case, the height difference caused by the unevenness can be compensated by independently adjusting the extension length of each adjustable leg 2, ensuring the upper frame remains level. Specifically, if the floor slab is tilted on one side and lower on the other, the adjustable leg 2 on the lower side needs to extend longer, while the one on the higher side needs to extend shorter. Operators can use a level to check the levelness of the upper frame and adjust the screw 22 of each adjustable leg 2 accordingly, extending the front, middle, and rear legs by different lengths. This creates a compensating height difference between the upper and lower frames, opposite to the direction of the floor tilt and at a matching angle, offsetting the effects of the unevenness and ensuring the upper frame and its supported cabinet are precisely level. Since each adjustable support leg 2 can be adjusted independently with an adjustment accuracy of millimeters, this device can adapt to various complex ground flatness conditions without the need for on-site leveling with shims, effectively avoiding problems such as uneven support point stress, deformation of the support frame, or cracking of the floor slab caused by uneven ground.

[0023] In the preferred embodiment of this application, reference is made to Figure 1 The adjustable outrigger 2 includes a threaded sleeve 21 and a screw 22. The external thread of the screw 22 engages with the internal thread of the threaded sleeve 21, and the screw 22 is threadedly connected inside the threaded sleeve 21. In use, rotating the screw 22 allows it to extend or retract relative to the threaded sleeve 21, thus achieving precise adjustment of the overall length of the outrigger. The adjustment range is up to 20mm, effectively adapting to uneven floor conditions in the computer room. Furthermore, a locking screw 23 is installed on the side wall of the threaded sleeve 21. After adjustment to the desired height, rotating the locking screw 23 locks the relative position of the screw 22 and the threaded sleeve 21. The locking screw 23 penetrates the side wall of the threaded sleeve 21, and its end abuts against the side wall of the screw 22, relying on friction to prevent the screw 22 from rotating during use, ensuring a stable outrigger height.

[0024] In the preferred embodiment of this application, reference is made to Figure 1 and Figure 3 The prefabricated adjustable support frame also includes diagonal braces 4. Diagonal braces 4 are placed between the upper and lower rectangular frames 1 to enhance the overall structure's resistance to lateral deformation. Connecting plates 41 are rotatably connected to both ends of the diagonal brace 4. The connecting plates 41 are flat and have connecting holes for bolt connectors 13 to pass through. During installation, the connecting plates 41 are fastened to the mounting grooves 12 of the support beam 11 via bolt connectors 13. Because the connecting plates 41 and the ends of the diagonal braces 4 are hinged, the diagonal braces 4 can automatically adjust their tilt angle according to the actual spacing of the frames, adapting to the spacing between the upper and lower frames, making installation flexible and convenient.

[0025] In the preferred embodiment of this application, reference is made to Figure 1 and Figure 4 The prefabricated overhead adjustable support frame is also equipped with a shock-absorbing module 5. The shock-absorbing module 5 is fixed to the support beam 11 by bolt connectors 13. The shock-absorbing module 5 includes a mounting bracket 51, a spring 52, and a rubber damper 53. The mounting bracket 51 is fixed to the support beam 11 by bolt connectors 13. The rubber damper 53 is used to contact the floor slab. The spring 52 is installed between the mounting bracket 51 and the rubber damper 53. When the cabinet is subjected to vertical or horizontal impact force, the shock-absorbing module 5 can absorb and buffer the impact energy, effectively protecting the safety of the cabinet and its internal equipment.

[0026] In the preferred embodiment of this application, all metal components constituting the prefabricated adjustable support frame, including the rectangular frame 1, adjustable legs 2, connectors 3, diagonal braces 4, and connecting plates 41, are hot-dip galvanized for corrosion protection in the factory. The galvanized layer thickness is not less than 85μm, which can effectively resist the humidity and corrosion in the computer room environment, eliminating the need for on-site touch-up painting and extending the service life of the support frame compared to traditional solutions.

[0027] The application process and implementation principle of this application embodiment are as follows: At the installation site, the cabinet layout and the position of the building's load-bearing beams are first positioned and marked, and the installation positions of each support point are marked. Then, the factory-prefabricated support beams 11 are assembled on-site using bolted connectors 13 to form upper and lower rectangular frames 1. The assembly process requires no welding or cutting. Adjustable legs 2 are placed between the upper and lower frames, and the legs are fixed to the frames using connectors 3 and bolted connectors 13. Simultaneously, the suspended support points of the connectors 3 extending outside the rectangular frame 1 are aligned and connected to the support columns or keels under the raised floor of the computer room, making the raised floor structure an auxiliary support point of the load-bearing system. During load transfer, the weight of the cabinet is sequentially transferred to the floor slab through the upper rectangular frame 1, the adjustable legs 2, and the lower rectangular frame 1. At the same time, part of the load is transferred to the raised floor support structure through the suspended support points of the connectors 3, forming a multi-path force transmission mode where the floor slab and the raised floor share the load, effectively reducing local pressure on the floor slab. Next, based on the actual flatness of the server room floor, a level is used to check the levelness of the upper frame. The screws 22 of each adjustable leg 2 are rotated to independently adjust the extension length of each leg, allowing the front, middle, and rear legs to extend to different lengths to compensate for ground inclination, until the upper frame reaches an overall level state, ensuring uniform force distribution at each support point. After adjustment, the locking screws 23 are tightened for fixation. Then, the diagonal braces 4 are installed, and the connecting pieces 41 at both ends of the diagonal braces 4 are fixed to the support beams 11 of the upper and lower frames using bolts 13, further enhancing the overall stability of the frame. In cases requiring vibration damping, vibration damping modules 5 are installed at the bottom of the adjustable legs 2 or on the support beams 11. After assembly, the cabinet is placed on the upper frame, and the cabinet base is fixed to the frame using bolts. When the server room layout needs adjustment, simply loosening the bolts 13 allows the entire support frame to be disassembled into standardized components, moved to a new location, and reassembled for reuse, achieving complete reusability.

Therefore, the present invention is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on the present invention are within the scope of protection of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
